摘要: The study was conducted to estimate requirements of energy and crude protein for maintenance, weight gain egg production Japanese quails in the period 67 107 days age. Two experiments were performed: one, determine maintenance protein, other, energy. Experiments a completely randomized design with four dietary levels offer replicates six birds. diets offered were: ad libitum (100%), 75%, 50%, 25% consumption (below maintenance). methodology used demand comparative slaughter. For estimation requirement gain, eight groups 15 reared separately, fed housed under 22 oC controlled temperature. From these poultry, three slaughtered at 5, 10, 15, 20, 25, 30, 35 40 trial. obtained by taking ratio content, efficiency use production. Prediction equations that requirement, quail include: metabolizable (kcal/bird/day) = 92.34*body weight0.75 + 6.23*weight 4.19*egg mass; (g/bird/day) 6.71*body 0.615*weight 0.258*egg mass.
